We follow the Sweden Float Tank Health Standard. A floatation tank is far cleaner than a swimming pool or a normal bathtub. The extremely high salinity (about 35%) provides a sterile environment where no microorganisms can reproduce. The water is also cleaned thoroughly between each session. Our tanks clean the water using a mechanical filtration system and UV light between each session. In addition to that, Peroxide is also used as a further step in the sterilization process.
